Specification of Letters Patent.

Patented June 2, 1914.

Application filed .Z'uly 18, 1913. Elerial No. 779.73%.

To all whom it may concern Be it known that T, iltLBERT P. Coonnann, a citizen of the "United States, and a resident of New York, in the county and State of the same name, have invented certain new and useful Improvements in Couplings, of which the following is a specification.

This invention relates to improvements in couplings and particularly to that class used in. connection with hose where it is joined to metal pipes and for other similar purposes where a slip joint is desired.

The object of the invention is to provide means whereby such connecting joints can be quickly and easily made without the use of tools or special appliances and which will hold the united parts safely and securely to gether until manually disassociated and in such manner as to avoid leakage of the matter transmitted through the connected tubular elements. This and other objects are attained by the novel construction of parts hereinafter described and shown in the accompanying drawing forming part or this specification, and in which:

Figure 1 is a transverse longitudinal section showing the interior construction of the invention in its simplest form. Fig. 2 is an end view of the same. Fig. 3 is a view similar to that shown in 1 but showing a modified construction. Fig. 41 is an end view oi the same. Fig. 5 is a longitudinal sectional view of the same, showing its application in connecting tubular elements. Fig. 6 is an end view of the same. Fig. 7 is a similar sectional view showing the device connecting a goose-neck with a gas hose, and, Fig. 8 is another like view showing its application.

The invention consists of a flexible elastic sleeve preferably of rubber molded into the shape shown, which is essentially conical at the ends 10, with an enlarged center portion 11 and having a passage 19- longitudinally therethrough, the sauce being substantially central at the extreme ends 13 and extending diagonally to the center forming an obtuse angle 14-; if the coupling thus formed he at tached at one end to a suitable hose or tube and slipped over a close fitting straight rigid tube at the other so that the tube will extend some distance past the apex 14;, it will cause the coupling to assume a shape in which the passage is nearly or quite straight and adhere securely to the tube.

In the other form shown in Figs. 3 to 8 inclusive, the sleeve is indicated to have cylindrical ends 20 with a bulbcd center 21 having extending substantially central of its length between the extreme ends a sinuous passage comprised of angularly disposed tubular openii'igs 23 connecting with others so as to form in effect a doubled obtuse angle at and 26. [is seen in 5, when a rigid tube is entered beyond the points 24: they will be held substantially parallel and in alineinent.

The application is indicated in Figs. 7 and 8 to a common form of goose-neck 30 connection, as from a. chandelier, the op posite end of the coupling being secured by the sleeve 31 to a flexible gas tube 32, having a thin metal inserted between, and extending to a drop light. heater or the like. The goose-neck is 111E. rted into the passsage in the coupling past the juncture oi the angulurly disposed portions of said passage, thereby deforming said coupling and causing the same to firmly grip the gooseneck. I am aware that rubber sleeves or sockets have long been used for like purposes but these have had a straight passage and lack the gripping properties of a coupling made in accordance with my invention, therefore I claim:

1. ill coupling of the class described comprising a yielding tubular member having a passage of substantially constant diameter 7 extending therethrough and opening at its opposite ends on the longitudinal median line of said member, one portion of said passage being disposed at an angle to the other, whereby a rigid tube of the same diameter as said. passage when iiiiserted in said pas sage past the junction at the angularly posed portions of the same will deform the In testimony whereof I have signed my tubular member and cause the same to firmly name to this specification in the presence of 10 grip the tube. two subscribing witnesses.

2. A couplin of the class described comprising ayieldi iig tubular member prdvided ALBERT COUHRANE' with an enlarged center portion and contain= l/VitnesSes: ing a sinuous passage-way, having two or WARREN E. lVILLIs, more distinct angles formed therein. BEN BROOKS.
